One person was injured Wednesday morning when a big rig crushed an sports utility vehicle Wednesday against a retaining wall on the Sam Houston Tollway in northwest Harris County, snarling traffic for miles.

The crash occurred about 5:45 a.m. on the westbound North Sam Houston Tollway near Bammel North Houston, according to Houston TranStar.

Officials said an 18-wheeler pinned a Chevrolet Tahoe against the wall. It was unclear what led to the crash or if the SUV had been stopped along the roadway.

Two people were inside the SUV. One of them was taken to a nearby hospital. Officials said the person had non-life-threatening injuries.

Traffic was jammed for miles as crews worked to clear the scene. Houston TranStar reported that the accident was cleared at 7:45 a.m.
